Message: <blockquote data-quote="someotherguy" data-source="post: 23056" data-attributes="member: 6178">The hubs on the SS's probably wear quicker due to the weight of 20" wheels/tires (and on my truck I ran 22's most of the time I had it) as compared to a 1500 that might have 16" factory wheels on it.There's also a whole range of part #'s you have to wade through when choosing replacements, even if you go with GM/ACDelco.  It's one of those GMT800 things where you could have 10 different choices for the same part depending on your truck configuration.  (and why I still can't find the correct power steering hose for the '06 SS.)Here's the one from her truck, can't remember the exact mileage at that time but it was between 100-120K.  We got the truck with 56K on it and it had the original cast aluminum 20" wheels.  I replaced them almost right away with much lighter Centerline 20" forged aluminum wheels and they've been on there since.  You can see some of the rollers had already given up, not surprising considering the lack of lube, and no seal against dirt or water intrusion.  So this one is an extreme example.  However, the ones on my truck failed near same mileage (wobbling) with no seal failure.[ATTACH=full]2838[/ATTACH]Example of some random truck in the impound lot, towed in from broken down on the road.  Extreme case of bearing failure.  Of course you can see in the pic he's running big, aftermarket heavy cast aluminum wheels.[ATTACH=full]2842[/ATTACH][ATTACH=full]2840[/ATTACH][ATTACH=full]2841[/ATTACH]Richard</blockquote>
